Q3) (B)

What is architectural design? Enlist different style and patterns of architecture. 

·       Architectural design represents the structure of data and program components that are required to build a computer-based system.

·       It considers the architectural style that the system will take, the structure and properties of the components

·       that constitute the system, and the interrelationships that occur among all architectural components of a system.

·     Representations of software architecture are an enabler for communication between all parties (stakeholders) interested in the development of a computer-based system.

·      The architecture highlights early design decisions that will have a reflective impact on all software engineering work that follows and, as important, on the ultimate success of the system as an operational entity.

·       The software that is built for computer-based systems also exhibits one of many architectural styles.

·       Each style describes a system category that encompasses

o   A set of components (e.g., a database, computational modules) that perform a function required by a system.

o   A set of connectors that enable “communication, coordination and cooperation” among components.

o   Constraints that de?ne how components can be integrated to form the system.

o   Semantic models that enable a designer to understand the overall properties of a system by analyzing the known properties of its constituent parts.

·       Data-centered architecture style

·       Data-?ow architectures

·       Call and return architecture

·       Object-oriented architecture

·       Layered architecture
